Preliminary
2.2
The data memory is partitioned into multiple banks
which contain the General Purpose Registers (GPRs)
and the Special Function Registers (SFRs). Bits RP0
and RP1 are bank select bits.
RP1
Each bank extends up to 7Fh (128 bytes). The lower
locations of each bank are reserved for the Special
Function Registers. Above the Special Function
Registers are the General Purpose Registers,
implemented as static RAM. All implemented banks
contain Special Function Registers. Some frequently
used Special Function Registers from one bank are
mirrored in another bank for code reduction and
quicker access.
2.2.1
The register file is organized as 128 x 8 bits in the
PIC16F722/LF722, 192 x 8 bits in the PIC16F723/LF723
and PIC16F724/LF724, and 368 x 8 bits in the
PIC16F726/LF726
register is accessed either directly or indirectly through
the File Select Register (FSR), (Refer to Section 2.5
“Indirect Addressing, INDF and FSR Registers”).
2.2.2
The Special Function Registers are registers used by
the CPU and peripheral functions for controlling the
desired operation of the device (refer to Table 2-1).
These registers are static RAM.
The Special Function Registers can be classified into
two sets: core and peripheral. The Special Function
Registers associated with the “core” are described in
this section. Those related to the operation of the
peripheral features are described in the section of that
peripheral feature.
